Description

Test socket

technical field

The present invention relates to a test socket, and more particularly, to a test socket configured for connecting a fully assembled electronic component to a testing device.

Background technique

Quality inspection of semiconductors, LCD modules, image sensors, camera modules, etc., to detect whether they are working properly by supplying operating signals and power that are the same as those applied to the electronic components actually mounted after each component is assembled , or similar.

A test socket is a device configured to connect an LCD module, camera module, or the like to a testing device so that signals from the testing device can be passed to the LCD module, camera module, or the like.

In this regard, Korean Patent No. 1006243 discloses a socket for detecting electronic modules. The socket disclosed by Korean Patent No. 1006243 includes: a main body part having a valve seat part on which an electronic module to be detected is seated; and a cover unit hinged to one side of the main body part and configured to be connected with The upper surface of the main body part contacts to selectively press the electronic module, and is configured to cover the upper part of the main body part to prevent the electronic module from coming out; the operation unit is provided on one side or both sides of the main body part and the cover unit to The cover unit is semi-automatically operated when the cover unit is closed; a clip unit configured to maintain the closed state of the cover unit by the operation unit; a pin assembly provided on the main body portion to be connected to the cover unit when the cover unit is closed an electronic module; and a printed circuit board connected to the pin assembly and electrically connected to the detection device.

In Korean Patent No. 1006243, an operation structure is formed in which, when the operator rotates the cover unit, a member (connection pin block or push block) provided on the cover unit presses the electronic module against the valve seat portion, thereby making The test socket connecting pin (hereinafter referred to as "connecting pin") is connected with the electronic module connector (hereinafter referred to as "connector").

However, Korean Patent No. 1006243 has the following disadvantages.

(1) Since the connecting pin and the connector are connected to each other in a state where the cover unit covers the electronic module, the electronic module and the detection device form a structure in which the electronic module and the detection device are electrically powered in a state where the operator's line of sight to the electronic module is blocked connect. Therefore, the operator cannot visually confirm whether the connecting pin and the connector are normally connected to each other.

When the test result confirms that the electronic module has good performance, the operator can consider that the connecting pin and the connector are normally connected. However, when the inspection result confirms that the electronic module is defective, it cannot be accurately determined whether the defect is caused by abnormal connection or a defect of the electronic module. Therefore, it is difficult to perform additional detection in this regard.

(2) When the operator manually rotates the cover, an operation structure is formed in which the connecting pin is connected to the connector, and the cover unit forms a turning radius of about 90 degrees on one side of the main body portion. Therefore, the space for installing the test socket occupies a space equivalent to the plane area of the main body portion and the height of the cover unit plus the space required for the operator's operation.

In the laboratory where the electronic module inspection process is carried out, various materials and equipment are installed in a limited space. For the convenience and efficiency of the inspection task, various materials and equipment are placed close to the operator. Therefore, as the footprint of the test socket in the laboratory increases, the convenience and efficiency of the inspection task decreases.

(3) Since the cover unit rotates to connect the connecting pin to the connector, the cover unit performs a curved motion while generating an external force for connecting the connecting pin and the connector, and the direction of the force changes instantaneously in the curved motion. Therefore, the rotational force of the cover unit is transmitted to the connecting pin and the connector in a direction inclined with respect to the connecting direction of the connecting pin and the connector (until the connecting pin and the connector are completely connected), and due to the external force, the connecting pin and the connector are The contact area between them creates friction, which is inconsistent with the ideal connection direction.

As a result, the connecting pins and connectors are damaged by friction. In particular, due to the gradual accumulation of damage caused by frictional forces, the life of connecting pins connected to a plurality of connectors may decrease rapidly.

In this regard, Korean Patent No. 759081 discloses a socket for detecting a camera module. The socket disclosed by Korean Patent No. 759081 includes: a main body part on which a camera module to be detected is seated; an operation unit connected to the main body part to facilitate its up and down movement; and a lift guide, the lift guide The parts are used to guide the lifting and lowering of the operating unit in the vertical direction; the clip unit is configured to fix the operating unit to keep the operating unit in a lowered state; the pin assembly is located on one side of the operating unit and is connected to a connecting pin to the camera module; a printed circuit board connected to the pin assembly; a connecting wiring line configured to connect the printed circuit board and the detection device; and a lens pressing portion provided with on the operating unit.

(4) In Korean Patent No. 759081, since the operation unit is formed with an operation structure that moves up and down in the vertical direction, the above problems (1) to (3) can be partially solved. However, since the lens pressing portion is located above the seat plate, the camera module may move toward the seat plate to collide with the lens pressing portion, and the camera module may therefore be broken. The lens pressing portion has a structural problem of interfering with the operator's line of sight to the seat plate.

Hereinafter, in order to facilitate understanding of the present invention, the type of the test socket 10 shown in the drawings (the connecting pin P is provided on the valve seat portion 110 ) will be described. A printed circuit board (PCB) is attached to the bottom surface of the base 100 . The connection pins P are connected to the PCB.

As shown in FIGS. 3-5 , a downward slope 121 is formed on the upper portion of the base 100 . More specifically, the upper side of the base 100 is provided with a guide member 120 , and the guide member 120 has an inclined surface 121 and a vertical surface 122 . The inclined portion forms a downward slope toward the valve seat portion 110 . The vertical surface 122 is formed below the inclined surface 121 .

As shown in FIGS. 1-3 , the first lever L1 and the second lever L2 are rotatably disposed on the base 100 , and the top cover 200 is formed with an engaging portion 220 that engages with the first lever L1 .

The plurality of first rods L1 are respectively rotatably connected to opposite sides of the base 100 . Each of the first levers L1 is rotationally biased toward the engaging portion 220 by a torsion spring (not shown). As shown in FIG. 2, when the top cover 200 is lowered, the connecting pin P is connected to the connector C, and the engaging portion 220 is engaged with the upper end of the first lever L1. When the engaging portion 220 is engaged with the first lever L1, the upward movement of the top cover 200 is prevented, and the connecting pin P and the connector C are maintained in a connected state. The lower end of the first rod L1 extends downward toward the base 100 .

As shown in FIGS. 4 and 5 , the second rod L2 is rotatably connected to one end of the base 100 . One end of the second rod L2 protrudes outward, and the other end of the second rod L2 is located below the other end of the first rod L1. When the operator presses one end of the second lever L2 in the state shown in FIG. 5 , the other end of the second lever L2 lifts the lower end of the first lever L1 to rotate the first lever L1 and release the engaging portion 220 and the first lever Engagement of L1. Since the first lever L1 and the second lever L2 are not essential parts of the present invention, their detailed descriptions will be omitted.

As shown in FIGS. 1-5 , the top cover 200 is configured to move the pressing module 300 in the vertical direction, and is formed to be able to move in the vertical direction above the base 100 .

A vertical shaft 130 is installed on the base 100 . Although not shown in detail, the base 100 is formed with a groove, and the vertical shaft 130 is inserted into the groove. A shaft groove SH is formed on the top cover 200, and the vertical shaft 130 is inserted into the shaft groove SH to enable the top cover 200 to move in the vertical direction. Therefore, in a state where the vertical shaft 130 is inserted into the shaft groove SH, the top cover 200 is in a state of being movable in the vertical direction above the base 100 .

A plurality of second elastic members E2 are inserted between the base 100 and the top cover 200 . The second elastic member E2 is configured as a compression spring. A plurality of installation grooves IH are formed on the base 100 and the top cover 200 , and the upper and lower ends of the second elastic member E2 are inserted into the installation grooves IH. The second elastic piece E2 is inserted into the mounting groove IH to prevent it from moving.

1 and 4 show a state in which the top cover 200 is raised to the highest by the restoring force of the second elastic member E2. The blocking member 131 is connected to the base 100 , and in the state shown in FIGS. 1 and 4 , the lower end of the top cover 200 is engaged with the blocking member 131 , due to the interference of the blocking member 131 , the top cover 200 cannot move upward any more, and remains state shown in Figures 1 and 4.

2 and 5 show a state in which the top cover 200 is pushed down by the operator (while the second elastic member E2 is compressed). When the external force (the pushing force applied by the operator) for lowering the top cover 200 to the state shown in FIGS. 2 and 5 is removed, the top cover 200 rises to FIGS. 1 and 4 by the restoring force of the second elastic member E2 status shown.

As shown in FIG. 3 , a pair of rails 210 on which the slider 310 slides are formed on the top cover 200 . The rail 210 is formed on the same extending plane as the downward inclination direction of the inclined surface 121 .

As shown in FIGS. 3-5 , the pressing module 300 is configured to press down the electronic component L when the top cover 200 descends. The pressing module 300 includes a slider 310 , a push block 320 and a rolling element 330 .

The slider 310 is configured to slide along the rail 210 , and is attached to the rail 210 through a pair of mounting portions 311 . When the mounting parts 311 are respectively mounted on the rails 210 , the rolling elements 310 can only move linearly along the axial direction of the rails 210 .

The push block 320 is configured to directly contact and press the electronic component L when the top cover 200 is lowered. The push block 320 is connected to the slider 310 . More specifically, the push block 320 is connected to an end portion of the slider 310 on the side facing the valve seat portion 110 . The push block 320 is made of elastic rubber or silicon material.

The rolling member 330 is configured to roll on the inclined surface 121 and the vertical surface 122 , and the rolling member 330 is formed in a cylindrical shape and is rotatably connected to the slider 310 by bolts or pins.

As shown in FIGS. 3-5 , the top cover 200 and the pressing module 300 are connected to each other through the first elastic member E1 . The first elastic member E1 is configured to make the rolling member 330 come into close contact with the inclined surface 121 and the vertical surface 122 . The first elastic member E1 is configured as a compression spring, and connects the slider 310 to the top cover 200 on the side opposite to the valve seat portion 110 . The slider 310 and the top cover 200 are respectively formed with holes, and both ends of the first elastic member E1 are engaged in the holes.

As shown in FIGS. 4 and 5 , the first elastic member E1 is configured to make the rolling member 330 come into close contact with the inclined surface 121 or the vertical surface 122 (pulling the slider 310 in a direction away from the electronic component L by restoring force). Therefore, when the top cover 200 is raised and lowered, the rolling member 330 rolls in a state of being in close contact with the inclined surface 121 or the vertical surface 122 .

In the state shown in FIGS. 1 and 4 , that is, in the state in which the top cover 200 is raised to the maximum position by the restoring force of the second elastic member E2 , the restoring force of the rolling member 330 by the first elastic member E1 and The upper ends of the inclined surfaces 121 are in close contact. At this time, the push block 320 is located below the top cover 200 , and the operator can easily seat the electronic component L on the valve seat portion 110 .

Thereafter, when the operator pushes the top cover 200, the pressing module 300 is pushed by the inclined surface 121 during the descending process of the top cover 200, thereby sliding over the electronic component L, and then descending toward the electronic component L in the vertical direction.

4 , R1 represents the moving path of the rolling element 330 when the rolling element 330 rolls on the inclined surface 121 , and W1 represents the moving path of the push block 320 when the rolling element 330 rolls on the inclined plane 121 . When the rolling member 330 rolls on the inclined surface 121 , the slider 310 moves along the track 210 , and the moving paths of the rolling member 330 and the push block 320 form the same angle with respect to the downward slope of the inclined surface 121 .

4 , R2 represents the moving path of the rolling element 330 when the rolling element 330 rolls on the vertical surface 122 , and W2 represents the moving path of the push block 320 when the rolling element 330 rolls on the vertical plane 122 . When the rolling element 330 rolls on the vertical surface 122 , the slider 310 no longer moves along the track 210 , and the rolling element 330 and the push block 320 form a moving path along the vertical direction.

The push block 320 is spaced apart from the electronic component L on the moving path W1, and presses the electronic component L downward (in the connection direction of the connector C and the connecting pin P) through the moving path W2. In the state shown in FIG. 5 , the connector C and the connection pin P are kept in a stable connection state by the pressing force of the push block 320 .

When the operator pushes the second lever L2 after the detection by the detection device, the top cover 200 rises by the restoring force of the second elastic member E2, and the pressing module 300 moves away from the electronic component L by the restoring force of the first elastic member E1 slide. That is, when the top cover 200 rises, the rolling member 330 rises in close contact with the vertical surface 122 and the inclined surface 121 due to the restoring force of the first elastic member E1, and the push block 320 moves in the opposite direction to the moving path W2 The path ascends, and then moves along the moving path in the opposite direction to the moving path W1, so as to be positioned under the top cover 200 again (see FIGS. 1 and 4 ).

In Korean Patent No. 1006243, an operation structure is formed in which, when the operator rotates the cover unit, a member (connection pin block or push block) provided on the cover unit presses the electronic module against the valve seat portion, thereby making The test socket connecting pin (hereinafter referred to as "connecting pin") is connected with the electronic module connector (hereinafter referred to as "connector").

However, Korean Patent No. 1006243 has the following disadvantages.

(1) Since the connecting pin and the connector are connected to each other in a state where the cover unit covers the electronic module, the electronic module and the detection device form a structure in which the electronic module and the detection device are electrically powered in a state where the operator's line of sight to the electronic module is blocked connect. Therefore, the operator cannot visually confirm whether the connecting pin and the connector are normally connected to each other.

When the test result confirms that the electronic module has good performance, the operator can consider that the connecting pin and the connector are normally connected. However, when the inspection result confirms that the electronic module is defective, it cannot be accurately determined whether the defect is caused by abnormal connection or a defect of the electronic module. Therefore, it is difficult to perform additional detection in this regard.

(2) When the operator manually rotates the cover, an operation structure is formed in which the connecting pin is connected to the connector, and the cover unit forms a turning radius of about 90 degrees on one side of the main body portion. Therefore, the space for installing the test socket occupies a space equivalent to the plane area of the main body portion and the height of the cover unit plus the space required for the operator's operation.

In the laboratory where the electronic module inspection process is carried out, various materials and equipment are installed in a limited space. For the convenience and efficiency of the inspection task, various materials and equipment are placed close to the operator. Therefore, as the footprint of the test socket in the laboratory increases, the convenience and efficiency of the inspection task decreases.

(3) Since the cover unit rotates to connect the connecting pin to the connector, the cover unit performs a curved motion while generating an external force for connecting the connecting pin and the connector, and the direction of the force changes instantaneously in the curved motion. Therefore, the rotational force of the cover unit is transmitted to the connecting pin and the connector in a direction inclined with respect to the connecting direction of the connecting pin and the connector (until the connecting pin and the connector are completely connected), and due to the external force, the connecting pin and the connector are The contact area between them creates friction, which is inconsistent with the ideal connection direction.

As a result, the connecting pins and connectors are damaged by friction. In particular, due to the gradual accumulation of damage caused by frictional forces, the life of connecting pins connected to a plurality of connectors may decrease rapidly.

In this regard, Korean Patent No. 759081 discloses a socket for detecting a camera module. The socket disclosed by Korean Patent No. 759081 includes: a main body part on which a camera module to be detected is disposed; an operation unit connected to the main body part to facilitate its up and down movement; and a lift guide, the lift guide The parts are used to guide the lifting and lowering of the operating unit in the vertical direction; the clip unit is configured to fix the operating unit to keep the operating unit in a lowered state; the pin assembly is located on one side of the operating unit and is connected to a connecting pin to the camera module; a printed circuit board connected to the pin assembly; a connecting wiring line configured to connect the printed circuit board and the detection device; and a lens pressing portion provided with on the operating unit.

(4) In Korean Patent No. 759081, since the operation unit is formed with an operation structure that moves up and down, the above problems (1) to (3) can be partially solved. However, since the lens pressing portion is located above the seat plate, the camera module may move toward the seat plate to collide with the lens pressing portion, and the camera module may therefore be broken. The lens pressing portion has a structural problem of interfering with the operator's line of sight to the seat plate.

The test socket 10 of the present invention is configured such that when the top cover 200 is lowered, the pressing module 300 moves above the electronic component L and presses the electronic component L in the connection direction of the connecting pin P and the connector C. Thereby, the problems (1) to (4) in the above-mentioned prior art are solved.

Even when the top cover 200 is lowered as shown in FIG. 2 , the position and angle of the connector C under the push block 320 can be confirmed. Therefore, the operator can intuitively confirm whether the connecting pin P and the connector C are normally connected to each other, so that the above-mentioned problem (1) in the related art can be solved.

As shown in FIG. 4 , the top cover 200 forms a non-rotating operating structure that moves in the vertical direction. The top cover 200 is lifted only by the height of the vertical surface 122 and the inclined surface 121 . Since the heights of the vertical surface 122 and the inclined surface 121 are not necessarily several tens of times or more of the connection depth between the connector C and the connection pins P or more. Therefore, the above-mentioned problem (2) in the related art can be solved by reducing the occupied height of the test socket 10 in the laboratory.

In addition, the push block 320 is spaced apart from the electronic component L on the moving path W1, and presses the electronic component L downward (in the connection direction of the connector C and the connecting pin P) through the moving path W2, thereby solving the above-mentioned related art Problem (3) in .

Further, when the top cover 200 rises, the push block 320 moves under the top cover 200 away from the upper side of the valve seat portion 110 , thereby solving the above-mentioned problem (4) in the related art.

The top cover 200 is formed to be movable in a vertical direction above the base 100 by the driver A. As shown in Figures 7 and 8, the driver A may be a pneumatic cylinder. Actuator A may be of the type using electric or hydraulic pressure.

The main body A1 of the driver A is connected to the lower end of the base, and the pull rod A2 of the driver A extends through the hole formed on the base 100 toward the top cover 200 . The pull rod A2 is connected to the top cover 200 by bolts. BH, which is not described above, indicates a hole for bolt insertion.

The vertical shaft 230 is provided on the top cover 200 . Although not shown in detail, the top cover 200 is formed with a groove, and the vertical shaft is inserted into the groove. The top cover 100 is provided with a hole, and the vertical shaft 230 is inserted into the hole to enable the top cover 200 to move in the vertical direction. In this way, in a state in which the vertical shaft 230 is inserted into the hole, the top cover 200 is in a state capable of moving in the vertical direction above the base 100 .

6 and 7 show a state where the top cover 200 is raised by the driver A, and FIG. 8 shows a state where the top cover 200 is lowered by the driver A and the connecting pin P and the connector C are connected to each other.

The slider 310 is configured to slide along the rail 210 , and is attached to the rail 210 through a pair of mounting portions 311 . When the mounting parts 311 are respectively mounted on the rails 210 , the rolling elements 310 can only move linearly along the axial direction of the rails 210 .

The push block 320 is configured to directly contact and press the electronic component L when the top cover 200 is lowered. The push block 320 is connected to the slider 310 . More specifically, the push block 320 is connected to an end portion of the slider 310 on the side facing the valve seat portion 110 . The push block 320 is made of elastic rubber or silicon material.

The rolling member 330 is configured to roll on the inclined surface 121 and the vertical surface 122 , and the rolling member 330 is formed in a cylindrical shape and is rotatably connected to the slider 310 by bolts or pins.

As shown in FIG. 7 and FIG. 8 , the top cover 200 and the pressing module 300 are connected to each other through the first elastic member E1. The first elastic member E1 is configured to generate a restoring force that brings the rolling member 330 into close contact with the inclined surface 121 and the vertical surface 122 . The first elastic member E1 is configured as a compression spring, and connects the slider 310 to the top cover 200 on the side opposite to the valve seat portion 110 . The slider 310 and the top cover 200 are respectively formed with holes, and both ends of the first elastic member E1 are engaged in the holes.

As shown in FIGS. 4 and 5 , the first elastic member E1 is configured to make the rolling member 330 come into close contact with the inclined surface 121 or the vertical surface 122 (pulling the slider 310 in a direction away from the electronic component L by restoring force). When the top cover 200 is raised and lowered, the rolling member 330 rolls in a state of being in close contact with the inclined surface 121 or the vertical surface 122 .

In the state shown in FIGS. 6 and 7 , the top cover 200 is raised to the maximum position by the driver A, and the rolling element 330 is in close contact with the upper end of the inclined surface 121 by the restoring force of the first elastic element E1 . At this time, the push block 320 is located below the top cover 200 , and the operator can easily seat the electronic component L on the valve seat portion 110 .

As shown in FIG. 8 , when the top cover 200 is lowered by the driver A, the pressing module 300 is pushed by the inclined surface 121 during the descending process of the top cover 200 , so that the pressing module slides above the electronic component L, and then moves in the vertical direction. decline.

When the rolling member 330 rolls on the inclined plane 121, the push block 320 is separated from the electronic component L, and when the rolling member 330 rolls on the vertical plane 122, the push block 320 goes downward (at the connection between the connector C and the connecting pin P). direction) press the electronic component L. In the state shown in FIG. 8 , the connector C and the connection pin P are kept in a stable connection state by the pressing force of the push block 320 .

After the detection by the detection device is completed, the top cover 200 is automatically raised by the driver A. When the top cover 200 rises, the pressing module 300 slides in a direction away from the electronic component L by the restoring force of the first elastic member E1 .

Therefore, when the top cover 200 is raised or lowered by the driver A, the speed of the top cover 200 can be controlled to be kept constant, so that the connector C and the connecting pin P are connected more stably. Since the operator does not need to press the top cover 200 or the like by hand, there is an advantage that the height occupied by the test socket 20 in the laboratory can be minimized.

According to the present invention, during the descending process of the top cover, the pressing module is pushed by the inclined surface to slide above the electronic components. Therefore, it is possible to provide a test socket in which the operator can observe the electronic module during the inspection, the height of the space in which the socket is installed is reduced, and the connection pins and the connectors are connected to each other in an ideal connection direction.

In addition, when the driver lifts the top cover, the pressing module slides in a direction away from the electronic component by the restoring force of the first elastic member. Therefore, it is possible to provide a test socket in which the connection of the connection pin and the connector is achieved by an automatic connection structure operated by mechanical force, rather than by manual operation by an operator.
